DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 781,175, dated January31, 1905.

Application filed October 29, 1904. Serial No. 230,449.

To all whom, it. may concern:

Be it known that 1, CHARLES BARRETT, a citizen of the United States,residing at Somerville, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements inDumping-Cars, of which the following is a specification.

This invention relates to an improved dumping-car used for theconstruction of railroad embankments and also in mines and in any workwhere it is desired to transport gravel, ore, and the like from-onepoint to another.

The object of the invention is to provide a cheap, durable, andconvenient device for the purpose specified which maybe easily operatedto dump from either side of the car-truck or from one end thereof.

The object of the invention is still further to provide a dumping-carwhich may be easily loaded with gravel or ore, as may be desired, and,further, to provide a dumping-car the different parts of which may beeasily discon' and arrangement of parts set forth in the followingspecification, and particularly pointed out in the claims thereof.

Referringto the drawings, Figure 1 is a vertical central longitudinalsection, partly in elevation, of my improved dumping-car. Fig. 2is anend elevation of the same, illustrating the car-body rotated to dumpfrom the side of the truck and tipped in dumping position in full lines,said car-body being shown in dotted lines in position ready to dump.Fig. 3 is a plan view of a portion of a truck-frame with a truck-frameplate fast thereto. Fig. 1

is a plan View of said truck-frame and truck- In the drawings, 8 is atruck consisting of a suitable frame 9, supported upon axles 10, fast towheels 11. A truck-plate 12, preferably formed of sheet metal and havingflanges 13 13 at opposite ends thereof, extends transversely across thetruck-frame 9, said flanges projecting downwardly outside and beingfastened to the opposite sides, respectively, of said truck-frame. Anintermediate plate 15 is pivoted to the truck-frame 9 by means of atransom-bolt 16. Said intermediate plate consists of a body portion 17,preferably formed of wood. A sheet-metal plate 18, having a flange 19 ateach end thereof, extends across and beneath said body portion, saidflanges projecting upwardly outside and fastened to the opposite sides,respectively, of said body portion. A plate 20 is fastened to the top ofthe body portion 17, at one end thereof, said plate having two trunnions21 integral therewith and upon opposite sides, respectively, thereof. Atthe opposite end of said body portion and fastened also to the topthereof are angle-brackets 22 22 and 23. It will be understood that thetrunnion-plate 20, body portion 17, sheet-metal plate 18, andanglebrackets 22 and 23 form, in operation and effect, a single piece.

The car-body 27 is preferably constructed of sheet metal, consisting ofa bottom 28, sides 29, and end 30, rigidly fastened together, and a gateor end 31, said gate being rigidly fastened to arms 32, one at each endthereof, each of said arms pivoted at 33, respectively, to oppositesides of said car-body. A chain 3 1, preferably upon each side of saidcar, is connected at one end thereof to an arm 32 and at the other endthereof to a hook 35, fast to the side of said car-body. The car-body 27is pivotally connected to the trunnion-shaft 21 by brackets 36, fast tothe bottom of the car-body, each provided witha vertical slot 37,opening through the under side of said bracket. Pins or bolts 38 extendacross the slot 37 beneath the trunnion-shaft 21 to prevent the car fromleaving the trunnions when said car is dumped into the position shown inFig. 2.

An adjustable stop-plate 39, formed of angle-iron, extends transverselyacross the car- The car-body is held in-a horizontal position, asillustrated in Fig. 1, by a staple 41, fast to the bottom of thecar-body and projecting through a slot 43, provided in the angle-bracket23 and locked thereto by a seal 44:, inserted in said staple beneathsaid anglebracket. It will be noted that the right-angleprojectingbrackets 22 form supports for the bottom of the car-body, as well as theanglebracket 23, when said car-body is in the position illustrated inFig. 1.

The advantages derived from my improved construction of car-bodyhereinbefore described are that the same is very cheap and easilyconstructed and operated, the truckplate 12 forming a cheap and verystrong means for tying and strengthening the different parts of theframe, as well as a plate upon which the intermediate plate locatedthereabove may swivel, and the sheet-metal plate upon the bottom of theintermediate plate also forms a very practical means for strengtheningthe wooden body portion of said intermediate plate, while the woodenbody portion forms a cheap and convenient means to which to attach thetrunnion-plate 20 and anglebrackets 22 to form a single structure orintermediate plate.

The general operation of my improved dumping-car is as follows: Assumingthat it is desired to dump material between the rails, said car istipped from the position shown in full lines to that shown in dottedlines, Fig. 1, the gate 31 being previously thrown into the positionillustrated in full lines, Fig. 2. Assuming that it is desired to dumpthe material upon either side of the truck, the carbody is rotated tothe position shown in dotted lines, Fig. 2, from the position shown infull lines, Fig. 1, and is then tipped to the position shown in fulllines, Fig. 2, dumping the gravel at one side of the track or truck. In

this position of the car-body the usefulness of the adjustable plate 39becomes apparent, said stop-plate being adjusted to strike against theties, and if it is desired to increase or diminish the angle of thebottom of the car-body when in the position illustrated in full lines,Fig. 2, said stop-plate is moved toward the left or right, respectively,in Fig. l and locked in position by means of the bolts 40. The advantageof being able to lock the gate 31 in a position midway between theposition indicated in dotted lines, Fig. 2, and that in which it isshown in full lines, Fig. 1, consists in the fact that a greater spaceis obtained between the main portion of the gate 31 and the bottom ofthe car-body, so that in loading or in unloading material upon or fromsaid car-bod y a greater space is obtained than when the gate is thrownback into the position shown in dot ted lines, Fig. 2.

Having thus described my invention, what I claim, and desire by LettersPatent to secure,
